Control of Foot and Root Rot of Lentil by using Different Management Tools

Abstract

The experiment was conducted at the sick plot, Pulses Research Centre, Ishurdi, Pabna, Bangladesh during 2011-12 to find out the effect of chemical, botanicals, biocontrol agents and healthy looking seeds against foot and root rot of lentil. Chemical, botanicals, biocontrol agents and healthy looking seeds were used as treatments in this experiment. The lowest foot and root rot (21.67%) was obtained from when seed treatment with Provax 200 (2.5 g/kg seed) which was followed by seed treatment with Trichoderma harzianum compost (1:5) and apparently healthy looking seeds, and the highest incidence (41.50%) was obtained from untreated control. The highest number of pod/plant (45.26), number of seeds/plant (87.80), weight of seeds/plant (2.44 g) and yield (1845 kg/ha) were recorded in seed treatment with Provax 200 (2.5 g/kg seed) which were followed by seed treatment with Trichoderma harzianum compost (1:5) and apparently healthy looking seeds, and the lowest of these parameters were obtained from untreated control.

Field application of Trichoderma spp. combined with thiophanate-methyl for controlling Fusarium solani and Fusarium oxysporum in dry bean

“…plus chloroneb produce the optimum combination treatment for damping-off control of cotton, followed by T. virens plus chloroneb plus metalaxyl. Khalequzzaman (2016) showed that seed treatment with Provax 200 (2.5 g/kg seed), followed by seed treatment with T. harzianum compost (1:5) gave the lowest foot and root rot disease incidence of lentil than the untreated control. In the present study, under field conditions, data reveal that the combination between Trichoderma spp.…”

“…Therefore, integration methods between biocontrol agents and the fungicides could be effective. The tolerance of several biocontrol agents to fungicides was studied by many workers over the world (Howell et al 1997;Wang et al 2005;Howell 2007;Vasundara et al 2015;Khalequzzaman 2016). In a previous study, we investigated in vitro the compatibility of ten Trichoderma spp.…”

Management of foot and root rot disease of fennel

“…Seed treated with Provax 200 (Carboxin + Thiram) showed least foot and root rot incidence of lentil at Madaripur and Jessore in Bangladesh (Anonymous, 2010). Khalequzzaman (2016) observed that the lowest foot and root rot (21.67%) was obtained from when seed treatment with Provax 200 (Carboxin + Thiram) (2.5 g/kg seed) in lentil. Anonymous (2014) found that root rot of Fenugreek could be controlled by seed treatment and soil drenching with Carbendazim 0.5 g/l.…”

“…Seed treatment and soil drenching with Provax 200 WP (Carboxin + Thiram) at 0.25% gave the highest number of seeds per umbel and weight of seeds per umbel which were followed by Seed treatment and soil drenching with Autostin (Carbendazim) at 0.25% and Seed treatment and soil drenching with Cabriotop at 0.3% treated plots, and the lowest of these parameters were recorded in Control plots. Khalequzzaman (2016) found that the highest number of pod/ plant (45.26), number of seeds/plant (87.80) and weight of seeds/plant (2.44 g) were recorded in seed treatment with Provax 200 (Carboxin + Thiram) (2.5 g/kg seed) in lentil.…”

“…It causes seedling death at early stage resulting very poor plant stand which ultimately produces very low yield. F. solani and S. rolfsii are soil-borne pathogens commonly occurs in the tropics and sub-tropics regions of the world causing root and foot rot of many crops (Aycock, 1966;Khare et al, 2014;Khalequzzaman, 2016;Khalequzzaman et al, 2016). Foot and root rot diseases may cause 100% seedling mortality in monoculture under conducive weather conditions for disease development (Begum, 2003).…”
